Poinsettia plant named ‘Duevikicin’

ABSTRACT

A new and distinct cultivar of Poinsettia plant named ‘Duevikicin’, characterized by its upright, outwardly spreading and uniform plant habit; vigorous growth habit; freely branching habit; large inflorescences with apricot-colored flower bracts; and excellent post-production longevity.

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘DUEVIKICIN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name ‘Duevikicin’.

The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create Poinsettia plants with attractive flower bract coloration.

The new Poinsettia plant is a naturally-occurring whole plant mutation of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number E-22-018, not patented. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the parent selection in a controlled greenhouse environment in Rheinberg, Germany in December, 2010.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since January, 2011 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Poinsettia have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duevikicin’. These characteristics in combination distinguish ‘Duevikicin’ as a new and distinct Poinsettia plant:

-   -   1. Upright, outwardly spreading and uniform plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Large inflorescences with apricot-colored flower bracts.     -   5. Excellent post-production longevity.

Plants of the new Poinsettia differ primarily from plants of the parent selection in flower bract color as plants of the parent selection had red-colored flower bracts.

Plants of the new Poinsettia can be compared to plants of Euphorbia pulcherrima Willd. ‘Fisvinci’, disclosed in U.S. Plant Pat. No. 14,107. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Poinsettia differed primarily from plants of ‘Fisvinci’ in the following characteristics:

-   -   1. Plants of the new Poinsettia were more vigorous than plants         of ‘Fisvinci’.     -   2. Plants of the new Poinsettia had larger leaves than plants of         ‘Fisvinci’.     -   3. Flower bracts of plants of the new Poinsettia were lighter in         color than flower bracts of plants of ‘Fisvinci’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Poinsettia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Duevikicin’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in Rheinberg, Germany during the summer in a glass-covered greenhouse and under environmental conditions and cultural practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day and night temperatures averaged 22° C. and light levels were about 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 12-cm containers and were pinched one time three weeks after planting the cuttings. Plants were 16 weeks old when the photograph and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
